As of 2022, Academia.edu collects potential publications by scientists based on their names. If people have common names or if there are multiple scientists with the same name, the users get numerous so-called "mentions", and are asked to identify which publications are actually theirs and which are not.

Keeping their account up-to-date and faultless therefore requires a paid account.
